金厂峪金矿难采矿体采场围岩稳定性数值模拟分析

Numerical simulation analysis of the stope wall rock stability of hard-to-mine orebody in Jinchangyu Gold Mine

针对金厂峪金矿难采矿体的情况 ,采用了分两层逆向和顺向推进房柱采矿法 ,应用FLAC软件 ,模拟沿矿体走向和倾向分层开挖过程中的围岩应力分布规律 ,为回采过程中采场围岩稳定性监测和围岩稳定性评价提供了理论依据。

According to the hard to mine orebody of Jinchangyu Gold Mine,the room and pillar mining was carried out in two slices along the right and wrong direction respectively.The stress distributive law of wall rock in the course of slice mining along the run and inclination of orebody was simulated using the software FLAC.This provided theoretical basis for monitoring the stability of stope wall rock and its appraisal.
